What should i do to start restoration

[versatile]

I have an old single cylinder stationary engine. Twin flywheels etc and water resivoir to cool it. No idea what brand. Rusted up and froze up from sitting outside for 35 plus years. How do i start? Should i soak the whole thing in something or what should i do?

I soaked mine in liquid wrench for about a month and then slowly started twisting the nuts and bolts. Complete success. No broken bolts. I used about two quarts of liquid wrench. The piston took the most effort and I did break one of the rings or it may have already been cracked. I drove the piston out with a four pound hammer and lots of 2x4's and liquid wrench. It took me about one week to get the piston out. For a replacement ring I discovered that Detroit Diesel 1200 hp engines had the same bore as my engine but the rings were half as thick therefore I placed two rings in the same slot. I still need to grind the valves but as it sits the compression is not great but ok.

I use diesel fuel to soak into long rusted parts, it penetrates well by itself. A few little taps on the bolts and covers and joints, will help loosen the joints. Use a small sledge 2-3 lb to gently rap on the pieces without breakage. These soundings will loosen most anything.
